Innovation Solution

A screen capture method that adapts to user-defined aspect ratios by determining a target screen corresponding to specified parameters, ensuring complete content capture without distortion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the screen capture image is stretched or compressed to adjust the aspect ratio, then the aspect ratio meets user needs, but the content becomes distorted and display effect deteriorates

Engineering Contradiction:

Improveaspect ratio adaptabilityVSAvoidcontent integrity

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent introduces a virtual screen dimension that matches the user-defined aspect ratio. Instead of distorting the captured image in place, the system creates a new dimensional space (virtual screen) with the desired aspect ratio and renders the interface elements into this new dimension, thereby preserving content integrity while achieving aspect ratio adaptability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent performs preliminary layout adjustment of interface elements before the screen capture operation. By pre-adapting the interface elements to fit the target aspect ratio on the virtual screen, the system ensures that when the screen is captured, the content is already optimized and no post-capture distortion is needed, thus maintaining content integrity.

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If the entire screen area is captured, then complete content is obtained, but the aspect ratio may not meet user needs

Engineering Contradiction:

Improvecontent completenessVSAvoidaspect ratio flexibility

Core Design Contradiction:

Loss of informationVSAdaptability or versatility

Solution Approach 1:

The patent segments the screen capture process into two independent stages: first capturing the entire screen area to ensure content completeness, then rendering interface elements onto a virtual screen with the user-defined aspect ratio. This segmentation allows the system to preserve all content while adapting the final presentation format.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The virtual screen acts as an intermediary between the captured full-screen image and the user's aspect ratio requirements. The system captures the complete screen content, then uses the virtual screen as a mediation layer to reorganize and present the content in the desired aspect ratio without losing any information.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If interface elements are re-rendered on a virtual screen with target aspect ratio, then aspect ratio is satisfied, but system complexity increases

Engineering Contradiction:

Improveaspect ratio customizationVSAvoidsystem structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a virtual screen as a software copy or representation of the physical screen, with the same functional capabilities but with a different aspect ratio. This copying approach allows the system to maintain the original screen hardware while creating an adaptable virtual representation, avoiding the need for physical hardware modifications.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The virtual screen is designed as a universal interface that can accommodate any user-defined aspect ratio. Rather than creating separate rendering systems for different aspect ratios, the single virtual screen mechanism can be configured to handle various aspect ratios, making the system multi-functional and reducing overall complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
